As far as AOC (I like that!) she's young, energetic and is a voice for the displaced, displaced by the current establishment, Trump being one of legion. Is she the panacea to change that, no, but she is the beginning of a change that must happen. In many ways it's like climate change. If an environment changes so much that there is not a way to survive in it, a species, an organization, a society adapts to that change or it will die. That is scientific, sociological, historical fact.
